hpplication filed December 31, 1908. $eria1 No. 470.1927.

Be itknown that I, FRANK 'C. FnRoUsoN, a citizen of the United States, and resident State of New York, have invented new and useful Improvements in Window-Screens, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. v

This invention consists in an improved construction of metal frames of wiiidow screens. a

The object of the invention is to simplify the construction of said frames and reduce the cost of manufacturingthe same. And to that end the invention consists in the novel construction of the screen-frames herein described and claimed.

In the accompanying drawings Figure 1 is a plan view of a window-screen embodying my invention; Fig. 2 is an enlarged transverse section on theline -X -'X- in Fi 1; Figs. 3 and t are enlarged longitudinal sections respectively on the lines -Y- Y- and -,VV in Fig. 1; and, Fig. 5 is an enlarged perspective view of portions of the Similar letters of reference indicate cor-- responding parts. -s denotes the wire screen, which is at-' tached. to its supporting-frame A. This frame is composed of sheet metal bars a, which are formed L-shaped in cross-section as shown more clearly *-in Fig. 2 of the drawings. In the inwardly disposed portions of said L-shaped bars are cut U-shaped slits as shown in Fig. 5 of the drawing. Upon the said portions of the bars aarest the margins of the wire screen-cloth -sand upon the said margins are placed metal slots ees-( ras shown in Fig: 5. The screen-cloth .s-- is fastened to the frame -A by means of the tongues c0- being bent from the plane of thebars -aa and passing through the screen-cloth and the slots ee-eand bent down onto the bands -d l as shownin Fig. 4 of the drawings. I i

--B-B" denote movable supplemental side frames, each of'which is formed in one piece of sheet metal, and consists of a plate --fextending across one of the end portions of the screen-frame and having its margins formed in the shape, of 3 side wall the exterior of the frame A- and are formed with inward folds --z' which ennate in tongues i whichare disposed to engage the inner face of the end bar (1,-- of the screen-fra ne to limit the outward movement of the supplemental frame -B, into .vvhich direction the said frame is auto matically moved by means of suitable springs ---lwhich may be either of the spiral type as sh own or any other well iznownform.

It will be observed that my invention produces an inexpensive adjustable screen, inasmuch as-the L-shaped bars -(L-(Z-- and the metal straps -.-(Z(Z can be obtained ready made. a The U-shaped slits b b-- and the slots +e-e-'are easily cut in said members by means ofsuitable dies. The bars aaoverlap at their ends and are easily and rigidly secured thereat by means of either rivets or solder, or other suitable devices. The supplemental. frame --l3 is also readily formedfrom a blank of sheet metal, by bending'tlie marginal portions "at the top, bottom and one side of said blank at right angles to the main portion thereof.

---0- denotes a depression in the plane of the plate f-- to serve as a handle for pushing the supplemental frame '-B .toward the frame Ar-to allow the screen to be removed from the window.

What I claim as my invention is: 1. As an. improved article of manufacture,

formed L-shaped in cross-section, and a movable supplemental side frame formed in one piece of sheet metal and consisting of a plate extending across the end portion. of the screen-frame and having its margins formed with a side wall and top and bottom flanges, said flanges being formed with inward folds engaging the free edges of the top and bottom bars of the screen-frame-and the inner faces thereof as set forth.

2. As an improved article of manufacture, a screen-frame composed of sheet metal bars formed L-shapedin cross-section, and a movable supplemental side frame formed in one piece. of sheet metal and consisting of a plate extending across the end portion of the screen-frame and having its margins formed 'a screen-frai'ne composed of sheet metal bars tions of said bars,

engaging the free edges of the top and bottom bars of the screen-frame and. the inner faces thereof and terminating in tongues disposed to engage the inner face of the and bar of'the screen-frame as and for the purpose set forth.

3. As an improved article of manufacture a screen-frame composed of sheet metal bars formed L-shaped in cross-section-and having U-shaped slits inthe inwardly disposed porstraps having transverse slots for receiving through them the U-shaped portions formed by the aforesaid slits and: passing through the interposed nun-gins of the screen; and movable supplemental side 15' wall and top and bottom flanges, sai'd flanges 20 bein formed with inward folds engaging the ree edges of thetop and bottom bars of the semen-frame and the inner faces thereof as set forth.
